Divide each side by 16
x = 3
He would maybe have 7.5 but I insist you the answer could be 8 too
Answer:
x^2-16
Step-by-step explanation:
A= (b)(h)
A= (x+4)(x-4)
x^2-4^2
x^2-16
Divide the miles by the gallons used for each car to find the miles per gallon, then compare them:
Blue car: 18 2/5 miles / 0.8 gallons = 23 miles per gallon.
Red car: 17 2/5 miles / 0.7 gallons = 24.86 miles per gallon.
The red car can travel farther on 1 gallon of gas.
